REPLACEABLE HESLS Fox SH01-:s

Filed Nov. 1:5, 1959 INVENTOR `ATTORNEY United relates i te'delantal-51e aiidi replaceable heelsffoi"shoes. n y,

lfhas he'etofebee prp's`ed` 'v heels for replacem'etl't when' excessivet the str tures as heretofore pro`pvts`ef'ill have n rlrduly cnipli"tedfso as toA be'costly fo manufacture;

id not etairiwth'e' heel tread members( in `iiel position' in ycomponentparts and inwhich the. com nentfpartsfare the: -h'el tread member tendsto' make the heel `Vtread r'nei'nber` tighter.

: Itis the further object of Athe ip`r =;sent invention to provide naconstruction having a replaceablegheelgtread .member and animprovedgonrletina retaining meehaaism between the heel treed. and therertigriivf the lieel secured to the sole of the shoe.

Other objects and advantageous features of the invention will beapparent from the description and claims.

The nature and characteristic features of the invention will be morereadily understood from the following description, taken in connectionwith the accompanying drawings forming part thereof, in which:

Figure 1 is a top plan view of the heel base portion of a shoe removedfrom the shoe and having the heel tread member attached thereto, partsbeing broken away to show the details of construction;

Fig. 2 is an underneath plan view of the heel base portion of the shoe,the heel tread member being detached therefrom;

Fig. 3 is a top plan view of the heel tread member removed from theshoe;

Fig. 4 is a vertical sectional view, enlarged, taken approximately onthe line 4`4 of Fig. 1;

Fig. 5 is a vertical sectional view, enlarged, taken approximately onthe line 5--5 of Fig. 1;

Fig. 6 is a fragmentary sectional View, enlarged, taken approximately onthe line 6-6 of Fig. l; and

Fig. 7 is a side elevational view illustrating the mounting of the heeltread member.

It should, of course, be understood that the description and drawingsherein are illustrative merely, and that various modications and changescan be made in the structure disclosed without departing from the spiritof the invention.

Like numerals refer to like parts throughout the several vlews.

Referring now more particularly to the drawings, for

extendmsi upward y ICC l I 6 d 'te move' the spring-"reigponiogn istemdesired position t`oY permitjfof locking, an actuatorpin' 30 is'provided; the inner' eiiidL 31 ef; which is vadapted4 tejien- `The pinhas, intermediate .its f itds, ,an easetfprfiiail ing of the spring legportion 25 in an open or disengaged position.

The pin 30 preferably has a slot 34 in the actuator end thereof for theinsertion of a tool (not shown) to press the same inwardly and turn thepin 30 for engagement of the oifset portion 32.

A heel tread member 35 Iis provided which may be made of any desiredmaterial but is preferably made of rubber of the desired shape and has abody portion with a plate 36, preferably of sheet metal and formed as astamping molded or otherwise secured therein. The plate 36 has a pair ofspaced hinge projections 37 which are adapted to engage over the rearmarginal edge 20 of the plate opening 19 to provide a rear hinge.

The plate 36 at the opposite or forward end is provided with a ledge 38extending therefrom. The ledge 38 has a slot 39 formed therein with anopening 40 and an upper margin 41 downwardly inclined to provide awedging action upon engagement by the spring leg portion 25.

The mode of attachment and detachment of the heel pad 35 will now bepointed out.

When -it is desired to initially apply a heel tread member 35 the pin 30is pressed inwardly with a suitable tool (not shown) engaging in theslot 34 thereof, the otfset portion 32. being engaged at the recess 33to hold the spring leg portion 25 away from the stop or limit tongue 27.The heel tread member 35 to be mounted is then brought to a position toengage the hinge projections 37 over the rear marginal edge 20 of theplate opening 19 and the ledge 38 is then moved upwardly through theopening 26, the slot opening 40 permitting the ledge 38 Patented July.19, 196e heel tread member 35 will thus Vbe retained in tight fixedrelation with. respect to theY heel base portionil. Y yIf replacement ofthe heel tread member 35 is` required by reason of wear, a tool, aspreviously pointed out,is

inserted in the slot 34 of the pin 30. The .pin 30 is pressed inwardlytoV disengage the spring leg portion 25 from the margin 41. Upon turningof -.the pin .to engage the offset portion 32 Vat the recess 33,.the-heel' tread member 35 may be swung downwardly about the pivotalaxis provided by the engagement ofthe hinge projections 37 with the edge20fof the plate opening 19. Y

A new heel tread member 35 may then be inserted as previously explainedand the pin 30 released so that the pin leg portion 25 can move to itslocking position in the slot 3-9. Y

I claim:Y l Y 1. A heel construction comprising a heel base portion anda heel tread portion with interior facing parts, one of said portionshaivng a plate secured on its facing part, said plate having spacedopenings therethrough at Vopposite ends thereof, ysaid plate having aspring mounted thereon on la side face thereof opposite its facing part,said spring having a leg extending over said side face and inintersecting relation to one of said openings, the other of saidportions having members projecting therefrom for pivotal engagement withmarginal portions of one of said openings in said plate and a ledgespaced from said members projecting therefrom and insertable through theother of said openings in said plate, said ledge having aAtransverseslot for locking engagement by said spring leg.
